I have a Dell Studio 1737 laptop running Vista Home Premium that is painfully slow.
In my testing I have tried all of the following:
Boot to KAV Rescue disk and check system for viruses. - Clean
Install Malwarebytes and perform a full scan - clean
Run msconfig and disable all non Microsoft services and all startup items
Remove and test the hard drive (Fujitsu) with Drive Fitness Test - Good
Create a new user profile which won't go past the welcome screen
The computer is still painfully slow; it takes over 45 minutes to logon or logoff.
I have thought about doing an OS reinstall but I don't want to go to that depth unless it will really fix something.
CPU constantly runs under 2% and Memory (4 Gb) constantly under 35%
What else do you suggest that I check?
